In the figure, line m is parallel to line n. The measure of ∠3
is 58°
. What is the measure of ∠7
?
1 answer
Since line m is parallel to line n, ∠3 and ∠7 are corresponding angles. Corresponding angles are congruent when two parallel lines are cut by a transversal. Therefore, the measure of ∠7 is also 58°.
